2015 Audi A4

The Audi A4 is a small sedan tasked with being all things to all people. For those seeking luxury, it has a plush interior and a comfortable ride; for tech-focused customers, it offers the latest connectivity and safety technologies; and for enthusiasts, it boasts well-tuned steering and tight handling, though the truly performance-minded will want to check out the more powerful S4 model.

Recent Changes
For the latest model year, the A4 gains more standard and available content for its Premium and Premium Plus trim levels.

Overview
Measuring 185 inches in length, the current A4 is 4.5 inches longer than the previous model and also larger than many of its rivals. This means it has a relatively spacious interior for the class, especially in the rear seat area. Audi's designers also clipped the overhangs to give the car sportier appearance, while the engineers moved the engine more towards the center of the car in order to back up the appearance with an improved weight distribution and better driving dynamics.

Stylistically, the car features a clear visual resemblance to the larger A6 and A8 sedans with similar cues like Audi's large corporate grille, a gently sloping roofline and LED running lights. The interior upholds Audi's reputation for exceptional cabin design with a simple, uncluttered yet stylish dashboard and good materials throughout.

Audi recently made the A4 available with the latest version of its MMI infotainment interface and Audi Connect, which makes the car a mobile Wi-Fi hotspot and also includes access to Google Maps - complete with panoramic views and high-resolution 3D satellite and aerial imagery.

Powertrain Options
Though prior A4s offered multiple engine choices, the latest model is powered solely by a turbocharged 2.0-liter four-cylinder engine. This motor produces horsepower 220 from 4,300 to 6,000 rpm, and 258 lb-ft of torque from 1,500 to 4,200 rpm.

Interestingly, despite having just one engine, there are three transmissions to choose from. The first is a six-speed manual transmission, good for a zero-to-60 jaunt of just 6.4 seconds, while returning 22 city and 30 highway miles per gallon. This of course is mated to the sporty quattro all-wheel drive system.

Opting for the convenience of a Tiptronic eight-speed transmission will lower fuel economy to 21 city, 29 highway, and add two-tenths to the zero-to-60 time. This model also features quattro all-wheel drive.

The final transmission option is the Multitronic CVT, which returns the best highway fuel economy of 31 mpg (the city rating is 21 mpg) and the slowest acceleration time of the three at 7.1 seconds. This is the only transmission to use FrontTrak front-wheel drive.

Those looking for more grunt than the A4's turbo four can offer should consider the Audi S4, which boasts a supercharged V6 with 333 horsepower.

Trim Level Breakdown
The A4 is offered with three trim levels: 2.0T Premium, 2.0T Premium Plus and 2.0T Prestige.

The entry-level 2.0T Premium model comes standard with leather upholstery, power-adjustable front seats, automatic single-zone climate control, a leather-wrapped steering wheel with audio and cruise control buttons and a ten-speaker audio system. A three-zone automatic climate control system, xenon headlights and LED taillights are newly standard, as is an S line exterior with a more aggressive body kit and 18-inch RS-design wheels.

To those features, the 2.0T Premium Plus adds heated seats, Bluetooth smartphone connectivity and iPod/iPhone integration.

The range-topping 2.0T Prestige adds a navigation system, a 14-speaker, 505-watt Bang & Olufsen premium sound system, rear parking sensors, an advanced key system and adaptive xenon headlights with LED daytime running lights.

Notable options include adaptive cruise control, blind-spot monitoring and Audi Drive Select, which offers a variety of different suspension, steering, transmission and engine calibrations.

The S line Style package brings 18-inch 10-spoke design wheels, all-season tires, Audi Xenon plus front lighting, dynamic headline range adjustment, LED taillights, high-gloss aluminum exterior window trim, S line fender badgers, S line bumpers, side sill blades, and stainless steel door sills with an S line badge.

The Black Optic package includes black exterior touches and 19-inch Titanium Rotor-design wheels.

Two new options packages are available for the Premium Plus. The Technology package bundles MMI Navigation plus, Audi connect, parking system plus and Audi side assist. A Sport plus package is also offered.

Occupant Safety
All A4 models are fitted with dual front, side thorax and side curtain airbags along with stability and traction control systems and electronic brake-force distribution with brake assist.

Optional on Prestige-trim models is Audi side assist, which monitors blind spots and fast-approaching vehicles.

Key Competitors
The Audi A4 is targeted at the perennial gold standard of sports sedans, the BMW 3-Series, as well as the improved Mercedes-Benz C-Class, the slightly larger Cadillac CTS and the luxurious Lexus IS 250.
